Definitions

  • the invention relates to a needle and a needle tube, in particular to a veterinary needle and a needle tube. Background technique
  • U.S. Patent No. 6,599,276, in 2000 proposed the use of ferritic stainless steel (430) and martensitic stainless steel (420) as the part of the steel pipe for the needle, so that it is on the metal detector of the existing meat factory. It is easier to detect broken needles.
  • the wall thickness of the needle tube was thickened and the strength was strengthened.
  • the cost of raw materials increased, and the wounds increased significantly when injected into livestock, which caused more pain to the livestock and may cause part of it. Livestock hurts the injector due to pain.
  • ferritic stainless steels Another problem with ferritic stainless steels is that the splicing performance is poor and the spliced portions are prone to rust.
  • the traditional 304 stainless steel has excellent splicing performance, and ferritic stainless steel is used as the needle steel pipe because of quilting. It is easy to rust and may cause hidden dangers.
  • U.S. Patent No. 6,488,668 also proposes a stainless steel needle tube made of a magnetizable metal material in stainless steel for the problem of broken needles, and defines a wide range of stainless steel.
  • this patent does not explicitly state which type of stainless steel material is used to make the veterinary needle, and, from its compositional range analysis, even the hardness of the needle tube made of stainless steel material within its range is still low. The detectability is also not high. Summary of the invention
  • the present invention provides a needle tube and a veterinary needle using the same, which solves the problem that the veterinary needle tube of the prior art is easily bent or broken, and is not easily detected by a metal detector after being broken.
  • the present invention provides a needle tube which is made of super ferritic stainless steel.
  • the invention further provides a veterinary needle comprising a needle hub and a needle cannula, wherein the needle cannula is made of super ferritic stainless steel.
  • the veterinary needle and the needle tube provided by the invention have high hardness due to the high ferritic stainless steel used, and the toughness is adjusted due to the inclusion of ⁇ , and the microstructure of the super ferrite itself is adjusted. It is a ferritin plasmid, which ensures the detectability. Therefore, in use, the needle tube is not easily bent and broken, and even if it is broken into the animal, it is easily detected by the metal detector. BRIEF abstract
  • FIG. 1 is a schematic view of a veterinary needle according to an embodiment of the present invention.
  • the needle 100 includes a needle tube 10 and a needle holder 20, wherein the needle tube 10 has a bottom for contacting the needle holder 20.
  • the tip 12 and the tip end 14 for contacting the injection site.
  • the needle tube 10 is made of stainless steel, but which stainless steel is used for veterinary use.
  • the performance of the needle has a large impact.
  • stainless steel can be roughly classified into ferrite, martensite, precipitation hardening, austenitic and duplex stainless steel. Later, super stainless steel was developed, including super martensitic stainless steel, super ferritic stainless steel, super austenitic stainless steel, super duplex stainless steel, maraging stainless steel, and the like. So far, after nearly a hundred years of research and development, stainless steel has formed a series of steel grades with more than 300 grades.
  • Stainless steel is available in a wide variety of applications. Different types of stainless steel generally have their own fixed application areas. Currently, in the field of veterinary needles, as previously mentioned, conventional 304 stainless steel is not easily detected by metal detectors. The brittleness of martensitic stainless steel (420) determines that it is not suitable for needle tubes. The hardness of ferritic stainless steel (430) is not sufficient and is not a good choice.
  • the needle cannula 10 is made of a super ferritic stainless steel material.
  • the super-ferritic stainless steel Due to the high chromium content of the super-ferritic stainless steel, it is generally considered to be very resistant to corrosion compared to conventional ferrites. Therefore, it is currently the preferred material for roofs and exterior walls such as houses near the coast, or Apply it to other corrosion resistant applications such as desalination or the organic acid industry.
  • the invention creatively applies super ferrite to the manufacture of veterinary needles, and experimentally improves the hardness, toughness, brittleness and detectability of the needle tube, plus its own corrosion resistance, Achieve good technical results.
  • the sum of C and N contained in the super ferritic stainless steel material is ⁇ 0.10 wt%.
  • the content of Cr, Mo and N contained in the super ferritic stainless steel material satisfies Cr + 3.3 Mo + 22 N > 35 wt%.
  • the super ferritic stainless steel material used in the present invention contains 0.01 to 5.0 wt% of Mo to adjust the toughness of the needle tube.
  • a super ferritic stainless steel having the following composition contents can be selected as a material for making a veterinary needle:
  • the steel tube must not be too soft and too brittle, otherwise many difficulties will arise during use.
  • the following table shows the comparison of Vickers hardness (after making a needle steel pipe, the Vickers hardness is measured by grinding, 10 pieces of 18G and 16G each)
  • the material proposed in this patent is made of steel pipe and its hardness can be compared with 304.
  • 30-2 is Cr30Mo2 super ferritic stainless steel.
  • 30-2 is similar to the detectability of conventional ferritic stainless steel 430. Significantly higher than the representative of duplex stainless steel 2205. 3, brittleness
  • the needle of the material used in the present invention is similar to the brittleness of 304, while the needle produced by the conventional ferritic stainless steel is obviously brittle.
  • the needle of the material used in the present invention is similar to the transverse hardness of 304, whereas the conventional ferritic stainless steel (430) produces a needle having a relatively small transverse hardness.
  • the veterinary needle and the needle tube provided by the invention can be compared with the 304, and can not only replace the traditional needle made by 304, but also has better performance, compared with the splicing performance, strength, toughness, rust prevention performance and crevice corrosion resistance. Needle made in traditional ferritic stainless steel (430).
